The connection between vision and memory is complex from "summary" of The Mind's Eye by Oliver Sacks

Vision and memory are not separate or discrete functions, but are deeply intertwined and interconnected in the mind. The complexity of this relationship is evident when considering the case of Lilian Kallir, a professional pianist who lost her sight due to macular degeneration. Despite being unable to see the keys, Lilian was able to play the piano flawlessly by relying on her memory and the tactile sense of her fingers. This remarkable ability to perform complex tasks without visual input illustrates the intricate ways in which vision and memory are linked. Moreover, the brain has the remarkable capacity to adapt and compensate for deficits in one area by relying on others. This phenomenon is exemplified by the case of Zoltan Torey, who lost his sight at the age of 21 due to a mysterious illness. Despite his blindness, Zoltan developed a keen sense of spatial awareness and was able to navigate the world with extraordinary precision. His ability to form mental maps and visualize complex spatial relationships without the aid of vision showcases the brain's remarkable ability to reorganize and adapt in the face of adversity. Furthermore, the relationship between vision and memory is not only evident in cases of sensory loss, but also in the realm of creativity and imagination. The painter and writer Jonathan I. had a condition known as Charles Bonnet syndrome, which caused him to experience vivid hallucinations of intricate geometric patterns. Despite being blind in one eye, Jonathan was able to create intricate drawings based on these hallucinations, tapping into a reservoir of visual memories and imaginative faculties. This demonstrates how memory and vision can interact in unexpected and creative ways, giving rise to new forms of expression and insight.
  1. The connection between vision and memory is a complex and multifaceted one that defies simple categorization. The stories of individuals like Lilian Kallir, Zoltan Torey, and Jonathan I. highlight the intricate ways in which these two cognitive processes interact and influence each other. By delving into these rich and varied examples, we gain a deeper understanding of the profound relationship between vision and memory in shaping our perceptions and experiences of the world.
